speedometer cleaning/repair on my '41 PU

[randy993]

Hello all,
I've tried search and couldn't find anything about speedometer cleaning/repair. I know it's there because a few months ago I was able to get my non working speedo to at least work a little. I've oiled it and got it moving but it's not reading correctly and the odometer doesn't work. I wanted to give it one more try before sending it for repair. Thanks in advance, Randy
